3 Claims.

' This invention relates to oil burners, and more particularly to oilburners especially designed for use in connection with hot water heatingplants, stoves or the like.

An important object of the invention is to provide an oil burner or thischaracter, constructed so that the oil will be completely vaporized onentering the fire-pot, to the end that the maxi mum amount of heat willbe insured, from a given quantity of oil, and at the same time providinga structure which will effectively operate when an inferior grade oifuel oil is used.

Another object of the invention is to provide an oil burner including abaille or deflector adapted to direct the heat from the burning gases,downwardly into the fire-pot, maintaining the fire-pot or the burnerhot, to insure the proper combustion of the fuel entering the burner.

Still another object of the invention is to provide a deflector directlyabove the fire-pot, which may be tilted laterally to facilitate thelighting of the fuel within the fire-pot, in starting the burner.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claims, it being understood that changes may hemade in the construction and arrangement oi parts without departing fromthe spirit of the invention as claimed.

Referring to the drawings Figure l is e. plan view of an oil humor,con-:- structed in accordance with the invention.

Figure 2 is a vertical sectional view taken on line 2-2 oi Figure l,

Figure 3 is a sectional view taken on line 53-8 01' Figure 1.

Figure 4 is a iragmental sectional view, illustrating a modified form orthe invention.

Figure it is a plan view of a rurther modified form of the invention,wherein the burner is of the circular type.

Figure ii is an elevational view partly in section, illustrating thebell-shaped deflector as provided with ahingedly mounted cover.

Referring to the drawings in detail, the body portion of the burner isindicated generally by the reference character 5, and as shown in thisparticular form, the body portion is rectangular in shape.

' Extending inwardly from the side walls oi the body portion, arehorizontal flanges 8 that are ill disposed in a horizontal line with thebottom of the tire door 7.

At the front and rear ends of the body portion, and connected with thehorizontal flanges 6, are inwardly extended flanges S which cooperatewith the flanges ll-in providing a supporting frame for the fire-pot 9.The ilre pot 9 is of a length slightly less than the length oi the bodyportion 5, provig air spaces at the ends of the fire-pot. The end wallsof the fire-quot are provided with rows of openings 56, while the mainportion of the lire-pot is solid, with theexception of rows of oneninrs96 arranged adjacent to the upper edges oi? the fliemo't, as clearlyshown by Fig. 3 oi the drawings.

A fuel pipe indicated at it extends into the bottom of the fire=pot t,at a point substantially intermediate the ends or the fire-pot.

The reference character, it indicates the baffle which normally closesthe upper portion of the fire-pot, the home being substantiallyhell-like in formation, the flared end thereof being supported withinthe lire-loot, as clearly shown by Fig. 3 of the drawings. I

'Bearlngs are formed in the end walls of the heme, and accommodate theshaft it to which the hafile is secured, so that movement of the shaftwill result in a relative rotary movement of the name to expose aportion oithe lire-pot for lighting purposes.

A plate indicated at it is secured to the upper surface of the ioaille,and is of a length to extend throughout the length of the the width ofthe plate lceing greater than the width of the hailie, providing wideextensions it overlying the curved sides of the traffic, in spacedrelation therewith, providing passageways.

Pins ll extend laterally from one edge of the home, and are designed tonormally rest on the horizontal flange ii, at the front of the loodyportion. At the rear edge of the hafie, the space it is provided, sincethe loaflle is of a width less than the width of the open side of thefire-pot 9. The pins it normally support the loaille against rotarymovement in one direction, but permit the hailie to rotate in a rearwarddirection. It will of course he understood that the rearward rotation ofthe tame is restricted by one edge of the plate as, which will contactwith the horizontal plate 6 extending along the rear wall of the burner.A handle indicated at 59 is formed on one end of the shaft 56, andaffords means whereby the bafie may be rotated or adjusted.

In the form oi the invention as shown by Fig. i of the drawings, theprinciple of the invention is carried out in the use of a substantiallybellshaped bailie indicated at 20. In this form of the invention, thebaffle is hingedly connected to one wall of the body portion 2i, as at22. In Fig. 5' of.

the drawings, the body portion of the burner is indicated by thereference character 23, and in this form of the invention, the bodyportion is circular. A circular flange at 24 extends inwardly from thewall of the body portion and provides a support for the fire-pot 25. Thebell-shaped baflle 26 is supported directly over the fire-pot 25 in thesame relation with the fire-pot as the bailie shown by Fig. 3 of thedrawings.

The battle 2B is supported on the shaft 21 mounted in suitable bearingswithin the fire-pot, the shaft being formed with a handle 28 foroperating the shaft and baflle secured thereto.

A slightly different form of the invention is shown by Fig. 6 of thedrawings. In this showing, the baffle is indicated by the referencecharacter 29, and is provided with a hinged cover 30 that is hingedlyconnected to one of the plates 3|,

which are secured to the baille. When lighting this form of burner, theclosure is swung upward- 1y, permitting easy access to a small quantityof oil which may be fed to the fire-pot directly thereunder, for theinitial heating of the fire-pot.

In the operation of the burner, a small quantity of fuel oil is fed intothe fire-pot, and the bell-shaped baille is tilted or moved, to expose aportion of the flre-p'ot, so that the fuel may be ignited for theinitial heating of the fire-pot. When the fire-pot becomes heated to adegree to insure combustion, the bailie is moved to its normal operatingposition, or to the full line position shown by Fig. 3 of the drawings.As the oil continues to flow into the fire-pot and is burned, theproducts of combustion are directed downwardly by the bell-shapeddeflector, from where they pass upwardly between the edge of thebellshaped deflector and the body portion, to the smoke-stack not shown,and which forms a part of the usual hot water boiler or furnace.

From the foregoing it will be seen that due to this construction, thevapors are forced or drawn through narrow channels and then mixed withair at the point of combustion, insuring perfect combustion of thelowest grade of fuel oil.

What is claimed is:

1. In an oil burner, a rectangular body portion,

having side and end walls a fire-pot mounted within the body portion,said fire-pot having an open top and a curved wall forming the bottomand sides of the pot, a substantially bell-shaped baille mounted withinthe body portion. the open side of the baille being disposed within thefire-pot in spaced relation with the curved wall thereof, providing anannular passageway between the fire-pot and baiile, a shaft extendingthrough the body end walls on which said bafile is rotatably mounted,said fire-pot having a plurality of openings formed therein and throughwhich air enters the fire-pot, and a pipe extending into the bottom ofthe fire-pot and through which fuel is fed to the fire-pot.

2. In an oil burner, a rectangular body portion, a fire-pot mountedwithin the body portion, said fire-pot having an open top, and a curved,wall forming the bottom and sides of the pot a substantiallybell-shaped baflle mounted within the body portion, the open side of thebaille being disposed within the fire-pot in spaced relation with thecurved wall thereof, providing an annular passageway, a shaft on whichsaid battle is mounted,'elongated extensions extending beyond the outersurface of said bailie at opposite sides thereof and in spaced relationwith the side walls of the body portion, and adapted to direct productsof combustion laterally, and a handle on one end of the shaft" wherebythe shaft may be rotated, and a pipe through which fuel is fed to thefire-pot. v

3. In an oil burner, a rectangular body portion having vertical sidewalls, a fire-pot mounted within the body portion, said firepot having acurved wall forming the bottom and sides of the pot, said fire-pothaving a plurality of openings formed therein adjacent to the upper edgethereof, a substantially bell-shaped baflle pivotally mounted within thebody portion, the open side the body portion.
